Headaches linked to bad weather

A survey of 7000 patients whose headaches were bad enough to prompt a visit to the emergency room revealed that for each 9 degree increase in temperature, the change of an attack in the following days increased just over 7%. Low barometric pressure readings, which usually accompany storms- were also linked with increased risk. Doctors who treat those who suffer migrains say 50% of their patients have reported suffering terrible episodes when the weather becomes extreme.
